Why is my backside droopy?

[Ollie]

If you mean that, it flies in nose up in a high pitch angle, it is because the wings have small span compared to chord. It is flying with a high angle of attack because of a high induced angle of attack.

Then why does the paper glider version glide level? If I changed thrust angle it would still not glide right w/ po. I think it is just too heavy relative to size. (reluctant to call it wing loading) The paper glider I remember was also pretty fast. Must make scaled speed be pretty high. When I moved the battery forward about 6" (which moved cg forward about 1 1/2") the model is starting to become "squirrely" as if cg was too far back on a conventional plane. Surprisingly moving cg forward had little effect on the attitude required to fly. Although less down angle was required on control bucket. The problem is not attaining the level angle so much as it then wants to fall out of the sky. Is the only answer lighter and faster? Have I hit the wall as far as this design will go??

Because the weight per unit of lifting area is higher. What is the weight and dimensions of the glider and of the larger model?

[Ollie]

At no lift, induced angle of attack is zero. The induced angle attack increases with the squared lift coefficient. If you increase the wing loading you must increase lift coefficient and total angle of attack. The airfoil angle of attack plus the induced angle of attack equals the total angle of attack of the wing.

...or have enough power to fly faster.

Some models can get 'caught' in a situation where they can only stagger around alomost at stall speed and never go fast enough to get the drag down enough to stay going fast. Sometimes a short dive gets them 'on step;' but its an unstaisfactory way to fly.

The angle is because the thing (you one wierd puppy) has to have more incidence on both rings.
That's an amazing flying machine! :)
